The SMF is a mine clearance equipment consisting of modules of spikes. These spikes are mode of specially hardened steel and are closely fitted to each other. This means that no mine can escape the spikes, not even if the mine is on end. The SMF mine clearance equipment consists of a system of modules which can be fitted together or work as separate units. The modules can be fitted to most working machines and they can be produced in small or large sizes. The small size version is 1 x 0,3m and the full size version is 3x1m. The weight varies from 400kg – 4000kg, depending on the size of the module.
Demining Equipment NSD 2001
The picture to the left shows the demining equipment fitted to an excavator which has centre steering system. The excavator makes it possible to pass through areas with fluctuating passability.
The flexibility, shown in the left version of the demining equipment, is enormously great since the excavator can rotate around its own axle. While standing in position, the range and rotation of the excavator makes it possible to clear areas comprising 75 square meters.
The demining equipment can be fitted to most working machines. E.g. the picture to the right shows the demining equipment fitted to a bulldozer.
The demining equipment can be produced in small or large sizes. The picture to the left shows a small demining equipment fitted to a mine clearance robot. The robot can then easily be remote-controlled into areas which are extremely dangerous or narrow.
The Three-step mine clearance equipment
The adjoining picture shows a prototype of the SMF – the Swedish Mine Fighter
The Swedish Mine Fighter works in three steps which makes it possible to disperse and lead off explosive forces which occur when a mine detonates.
Because of its three-step function, the SMF does not cause any damage to the ground when clearing areas from mines. It rather improves the fertility of the soil when leaving small holes in the ground after the area has been cleared.
The spikes make it possible
The spikes fitted to the Swedish Mine Fighter are closely fitted to each other which makes it possible to destroy or detonate even the smallest mine and it does not mater if the mine is on
Successful test with the SMF
During a test performed and inspected at the Swedish Army Mine Clearance Centre, antipersonnel mines of type DM11 were used. The DM11 mine is a small plastic mine which is very hard to discover. The mines used at the test were placed at various depths (0-30 cm) and they had no possibility to escape the spikes which penetrated the ground and either destroyed the mines or caused them to detonate.
Small mines – terrible power
Small plastic mines have a tremendous explosive force. Despite damage to the ground when a mine detonates, there is no damage to the Swedish Mine Fighter since the construction of the Swedish Mine Fighter is made to disperse the explosive forces of a detonation.
The SMF works in three steps in order to disperse and lead off explosive forces caused by a detonation. It does not destroy the ground where it operates. It rather improves the fertility of the soil when leaving small holes in the ground when the area has been cleared. The SMF is easy to handle and it operates on broken ground as well as on flat ground. The SMF is also easy to assemble, no special tools are required.
